Horizon Client computer
or client access device
Because MMR ooads media processing from the server to the client, the
client has the following minimum hardware requirements.
Processor: Intel Pentium 4 or AMD Athlon dual-core
Processor speed: 1.5 GHz for common case, or 1.8 GHz for Full HD
Memory: 2 GB RAM
Video adapter: Hardware accelerated
You must install one of the following libraries to avoid video playback issues:
n
GStreamer core library and gstreamer-mpeg 0.10
n
GStreamer core library and uendo 0.10
On SLED 11 SP4, if you encounter video playback issues such as a black
screen, remove the library libvdpau.
On HP thin clients, you must remove the
le /usr/lib/gstreamer-0.10/libgstfluvadec.so to avoid video playback
issues such as a Horizon Client crash or a black screen.
On Dell Wyse thin clients, video playback might not work with the pre-
installed uendo library. To resolve the problem, contact Dell support to
obtain the latest uendo library.

more information, see “Horizon Client Conguration Seings and Command-Line Options,” on page 27.
Requirements for Using Flash URL Redirection
Streaming Flash content directly from Adobe Media Server to client endpoints lowers the load on the
datacenter ESXi host, removes the extra routing through the datacenter, and reduces the bandwidth
required to simultaneously stream live video events to multiple client endpoints.
The Flash URL redirection feature uses a JavaScript that is embedded inside a Web page by the Web page
administrator. Whenever a virtual desktop user clicks on the designated URL link from within a Web page,
the JavaScript intercepts and redirects the ShockWave File (SWF) from the virtual desktop session to the
client endpoint. The endpoint then opens a local VMware Flash Projector outside of the virtual desktop
session and plays the media stream locally. Both multicast and unicast are supported.
This feature is available when used in conjunction with the correct version of the agent software. For View
5.3, this feature is included in the Remote Experience Agent, which is part of the View Feature Pack. For
View 6.0 and later releases, this feature is included in View Agent or Horizon Agent.
